Okay, let's start over then..
1) San Jose, CA
2) Experiencing latency issues with my game (Guild Wars 2) and TeamSpeak3. TS3 shows my ping hovering around 600~1000ms. Ping quality is "F" from pingtest.net. I've done multiple tests hard wired to modem and on router. Would still give grade "F" with a ping of 600-1000ms and jitter from 700-900ms.
3) I've been having this ping issue ever since yesterday. I've changed the IP once since my IP yesterday was geolocated somewhere in New Jersey. My IP today says it's located in my city of San Jose.
